RIP Malcolm. ACDC songs are among the first songs that any guitar player learns. And they are still the most fun to play. He's probably the most overlooked musician in rock music, and I think he enjoyed it more like that.

The news comes via TMZ, who say that the 67-year-old Cassidy was brought to the hospital three days ago, and his condition has been deteriorating. They're saying he could die if he doesn't receive a liver transplant immediately, and that he has kidney failure, as well. Cassidy's family has been arriving at the hospital to be at his side.
